Remove index cover. 2. Remove index from gas meter. 3. Mount AMR transmitter onto gas meter. 4. Assemble index and cover onto AMR transmitter. 5. Initialize AMR transmitter with HHT. Remove index cover 1. Use small flat screwdriver to punch out the seals that cover two (2) of the four (4) index cover screws. 2. Remove and properly dispose the four (4) screws holding the index cover onto meter, with flat screwdriver. If two (2) or more screws shear off during the cover removal (or were previously sheared off), the meter will need to be replaced by a qualified utility representative. Reinstall any index cover screws that were removed and cap with seals if possible. Enter the appropriate information in the Mint HHT and skip to the next work order. 3. Remove the index cover and dispose of properly. AMR Transmitter Mounting Instructions for American Meter AC250, AL175, AL250, AL5B, AL225, AL425 5 Remove index 1. Remove and properly dispose the two (2) screws holding the index onto the meter, with small flat or Phillips screwdriver. 2. Remove the index and carefully clean any debris from it. Inspect for proper index operation by turning the input shaft and verifying that the gearing turns freely. Also, inspect the index for any missing or broken hands. Place the index, or a new index if necessary, on a clean surface near you for reinstallation later. 3. With a putty knife, scrap away any gasket material that remained on the meter when the index cover was removed. AMR Transmitter Mounting Instructions for American Meter AC250, AL175, AL250, AL5B, AL225, AL425 6 Mount Transmitter on meter Insure the four (4) mounting screws are available and within reach. Place the AMR Transmitter onto the gas meter, aligning the Transmitter’s shaft with the gas meter’s male or female wriggler; adjust the Transmitter shaft’s position by holding it on the front side, and insert pin into hole. 1. While holding the Transmitter in place, check that the shafts are aligned by gently rotating the Transmitter’s shaft with your other hand. There should be just a slight freedom of motion. 2. Attach the Transmitter to the meter using the four (4) mounting screws with #3 Phillips screwdriver. Place all screws, then torque down two (2) diagonal screws. Check shaft alignment again, then tighten the last two (2) screws. 3. Should two (2) or more screws shear or strip during the installation, the meter will need to be replaced by a qualified utility representative. Remove the transmitter and reinstall the index and index cover on the meter with the original screws. Enter the appropriate information in the Mint HHT and skip to the next work order.

Insure the two (2) index screws are available and within reach. 2. Install the right side index screw to its place in the index (use tweezers if more convenient). Skip this step if assembling a plastic index. 3. Insert #1 Phillips screwdriver to hold screw in place, while placing the index onto the Transmitter, then insert the screw just 2-3 turns, so that the index fits loosely on the Transmitter. In case of a plastic index, or an index with open screw positions, first insert the right screw 2-3 turns and then slide the index mounting slot behind the screw head. 4. Align the index male or female wriggler with the Transmitter’s shaft; adjust the wriggler’s position by holding the proving hand on the index front side, and insert pin into hole.

Use left hand to install the screw and secure index into place. With plastic index: 6. While the index is still a bit loose, centralize its position. Check that the motion is smoothly transferred and t…

Theory of Operation General The device is a Direct Sequence Spread Spectrum burst transmitter for Automatic Meter Reading (AMR) of gas meters. This device is mechanically designed to fit on American Meters residential meters and is part of a family of products designed to cover the majority of meters, both residential and industrial, in use in the USA. The interface with the meter comprises a magnet mounted on a shaft extended from the meter and two reed switches mounted on the board of the unit. This battery operated device is maintained most of the time on stand-by and wakes up to accept and count pulses from the meter interface. Once every pre-programmed number of hours the device wakes up and generates air message containing information on the meter reading. The air message is a burst DS SPSP transmission in one of number of pre-defined channels. These messages are collected by network of base stations that covers the area of service. The base station decodes the upcoming messages and sends them via a backbone connection to a central computer, the Data Operation Center (DOC). Signal Description • Operation frequency band - 904.6 MHz (channel 5) to 925.4 MHz (channel 57). • Channel spacing - 0.4 MHz. • Modulation technique - DBPSK, Direct Sequence Spread Spectrum. • Chip rate - 1 Mchip/Sec. • Spreading sequence - 255 Maximal Length sequence. • Raw data rate – 3921 Bit/Sec. • Preamble length – 300 bits. • Raw data length – 320 bits. • Error correction code – Convolution code, R=1/2, K=5. • Interleaver depth – 20 bits. • Message duration – 158mSec. Signal Generation The transmitter is a direct conversation burst transmitter. The transmitter comprises synthesized local oscillator, that works with 15 MHz crystal reference and generates carrier in the 902 - 928 MHz band with channel spacing of 0.4 MHz, printed modulator that receives carrier signal from the synthesized local oscillator and base-band signal from the signal spreading module and generates direct sequence spread spectrum signal, and power amplifier module that amplifies and feeds a printed antenna with 29dBm signal.

Radiated Emission, For Low Frequency Transmitter (65.8 kHz) 6.1 Test Specification 9 kHz-30 MHz, FCC, Part 15, Section 15.209 6.2 Test Procedure The E.U.T. operation mode and test set-up are as described in Section 3. A preliminary measurement to characterize the E.U.T was performed inside the shielded room at a distance of 3 meters, using peak detection mode and loop antenna. The preliminary measurements produced a list of the highest emissions. The E.U.T was then transferred to the open site, and placed on a remote-controlled turntable. The E.U.T was placed on a non-metallic table, 0.8 meters above the ground. The configuration tested is shown in Figure 3. The frequency range 9 kHz-30 MHz was scanned, and the list of the highest emissions was verified and updated accordingly. In the frequency range 9 kHz-30MHz, the loop antenna was rotated on its vertical axis. The antenna height (center of loop) was 1 meter at a distance of 3 meters. The E.U.T. was operated at the frequency of 65.8 kHz 6.3 Test Data JUDGEMENT:Passed by 49.2 dB The EUT was tested and it met the requirements of the FCC Part 15, Subpart C, specification. The margin between the carrier level (65.8 kHz) and the specification limit was 49.2 dB. All other emissions were at least 40 dB below the limit. See details in Figure 5. Note: Based on FCC Part 15, Section 15.201 no certification is required for this low frequency transmitter. TEST PERSONNEL: Tester Signature: _________________Date: 28.12.04 Typed/Printed Name: E.
